| The aim of this study was to determine the chemical composition and fatty acids profile present in Argentine anchovy (Engraulis anchoita) northern population as a function of fish size and fishing area (SW Atlantic Ocean, Argentine Sea). Samples were collected during the northern stock assessment cruise of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) carried out on board of FRV Capitán Oca Balda in Spring 2008 (OB-02/2008). The fishing trawls were performed between 34º 35' S and 40º 19' S. The area was divided in two zones: the northern, between 34º S-38º S, strongly influenced by the mixohaline waters of the Río de la Plata River estuary and the southern, between 38º S-41º S, that included the El Rincón coastal area. In each... |

| Parasitized and non-parasitized hake fillets obtained at fish processing plants were compared in order to assess the efects of Kudoa rosenbuschi myxosporidia on muscle of Merluccius hubbsi. The following studies were carried out: a)incidence and severity of parasitism; b)proteolytic and spoilage at a histologic level; c)pH and proximal composition in parasitized and non-parasitized fillets; and c)parasitism action on gelified products. Gel strength, elasticity and organoleptic level in gelified products were lower for parasitized samples. Recommendations are put forward as to conditioning and cooling of the catch and subsequent processing in order to lessen the effects of parasitism. |

| The anchovy (E.anchoita)is one of the most abundant species in the Argentine Sea. Distributed in between latitudes 34°S and 48°S, it has only been caught, traditionally, along the coasts of Buenos Aires Province - particulary in the vicinity of Mar del Plata. Anchovy-like items are exported both to producing and consuming countries. During the last three years markets have been lost. In order to regain them and to develop new ones, particularly in Europe it shall be necessary to compete with products that are well-priced and of the high quality and have a substantial aggregate value. The anchovy domestic market could be enlarged- with certain limitations- be developing new products. |

| The biochemical composition and energy content of muscle, liver and gonads of Merluccius hubbsi females during the reproductive cycle were assessed. Adult females (44-50 cm total length) were caught in the Patagonian area (43~' S-45~' S). Condition factor (K) and hepatosomatic index (HSI) were estimated. Proteins and lipids in each tissue were determined. Besides, water and ashes content in muscle was analyzed. In all tissues the biochemical components underwent variations during the reproductive cycle. During the process gonads showed a significant drop in protein and lipid content (P < 0.01). In muscle, a decrease in proteins (P < 0.01) and lipids in the postspawning period was observed; the percentage of both components increased during the... |
